My current Hartke 2115 combo isn't really cutting it anymore. It now seems really cold and brittle sounding. I've also had to replace the 15" driver 4 times due to various mishaps, some of which were my fault and some of which weren't. From the looks of it, it just couldn't take the Hartke 2000 head's volume past 3 (with my passive bass turned all the way up), so oftentimes I couldn't get to a good volume so I could hear myself over the mix without fearing that I'd destory the driver again. So, being that I don't have much else besides bass making me happy right now, I'd like to get a new setup. I would a speaker setup that's better able to cover a full range of sound so my tone sounds fuller. Lots of bottom like the 15", but more punch. Would a 2X12 be enough in that regard? I'm willing to get another cab in the future, but I need to start with just one cabinet right now and I'd like something to cover the fundamentals but still get heard. Also, I've been thinking about getting an Ampeg V4B-H head. I like the sound of a good, warm tube amp and the pricepoint of a used V4b-H is appealing. I'm just not sure if it's enough for my needs, being only 100 watts and all. I know tube amp can sound louder and wattage isn't everything, so now I'm just confused. It's not like I'm playing with a band when I'm in the music store either, so I can't tell when I try these things out. Can you guys suggest a minimum wattage for small clubs & auditoriums? If you guys need to know, I play a lot of rock, metal, hip-hop, punk & rather bad pop music (not by choice) so versatility counts for a lot. I'm sorry if this post is too long. I don't know what you guys need to know and what you don't. Thanks for all your help.
